Updated On: Jul 2, 2026
- Symbiotic relationship between plants
- Competition for light among plants
- Chemical inhibition of one species by another
- Mutualistic interaction between fungi and roots
Show Solution

The Correct Option is C
Approach Solution - 1
Allelopathy involves the release of biochemicals (allelochemicals) by one plant species that influence the growth, survival, or reproduction of other species. For example, black walnut releases juglone, inhibiting the growth of nearby plants.

Approach Solution -2
Break Down the Word: 'Allelo-' relates to 'other', '-pathy' relates to effect/suffering — together, one plant chemically affecting another.
Allelopathy is the release of biochemicals (allelochemicals) by one species that inhibit growth in nearby plants, like black walnut's juglone suppressing neighboring plants — matching option 3.
Symbiosis and mutualism both describe MUTUALLY beneficial relationships — the opposite of allelopathy's inhibitory effect — and light competition is a purely physical, not chemical, interaction.
